- RADIOTUBE SOCKET. V

* Application filed October as, 1926.. man no. 14am.

. This invention relates to sockets for radio tubes, and more particularly to clips or terminals for use with such devices, and has for its principal object to provide an extremely a simple construction of clip of the character described, capable of being readily applied to a panel or base and forming therewith a tube socket capable of supporting tubes with varying lengths of prongs or terminals,

in without requiring any "adjustment thereof.

The invention may best be understood by reference to the accompanying drawing, in which Figure 1 is a lan view of a topview of a basepanel to w ich' my improved form of clip is applied to form a tube socket, with. parts broken away to show the position of one of the clips.

Figure 2 is an enlarged viewin perspecfl tive, showing one ofthe clips, Figure -3 is a sectional view 3F3 of Figure 1,

1 taken on line 4-4 of Figure 1, Figure 5 is a sectional view taken on line 55 of Figure 1.

taken on line Referring. now to details shown in the.

drawing, indicates a. subpanel or base, having a plurality of holes, 11, 11, (herein four) arranged and disposed to receive the four base terminals or prongs 12, 12 of the ordinary commercial form of radio tube or audion. In the drawing,.Fig'ure 1, these prongs are shown in section the remaining 3:) parts of the tube being omitted, as unnecessary for an understanding of the present invention.

In association with each-of said terminalholes 11,-11, I provide a metal clip 15. This 4o' clip is formed of a. sin le relatively flat piece of metal, preferably s eet metal, formed by ordinary stamping and bendingoperations 1n the shape shown which consists in two upright wing portions 16, 16, joined together apart at the opposite end to form a pair of spring contacts 18,18, arranged in registering position beneath its terminal hole 11, as clearly seen in the drawings. These spring contacts engage opposite sides of the tube terminals 12, when the tube is inserted in place, and hold saidtube firmly by spring tension.

Means for securing the clip in place comprises a pair of laterally extending supre 4 is an. enlarged. sectional viewnear one end bya portion 17, and spaced porting parts19, 19, adjacent the rear end of the clips and adapted to engage-the under surface of the base 10, a pair of upwardly extending. rojections .20, 20, which are normally continued upwardly in the same plane as the mam wing portions 16, 16, at a point intermediate their ends, and another, shorter,

pair of projections 21, 21, adjacent the extreme rear end of the clip, all as shown in Figure 2.

In applying the cli to the base panel 10,

the latter is provide with a pair of apertures 22 and 23, in ali cut with each terminal hole 11, (see Flgure 1). The larger pair of projections 20, 20 are passed upward ly through the innerhole 22,'and the upper ends are then turned or bent outwardly so as to "clamp the clip with parts 19, 19, and

upperedge's' 18, 18', of wmgs 18, 18, held againstthe lower surface of the panel, but permitting freedom of lateral bending of the outer ends of terminal contacts 18, 18. The shorter projections 21, 21, fit in the rearmost hole 23, so as to restrain the clip from twisting movement. e

Electrical connections may be madewith each clip by soldering to a terminal piece 26, formed at the bottom and rear end thereof, as shown, or else, by riveted connection with the laterally projecting supporting arts 19, 19, the latter being shown with oles 19, 19 for this purpose, if desired.

The use of the device above described will now be manifest to those skilled in the art. The clip is capable of .being manufactured most economically and in large uantities, and of being applied to base pane s with a minimum amount of labor or expense. The resulting device forms a superior holder for standard radio tubes, without requiring any changes, for tubes having terminals of difierent lengths. v

I'claim as my'invention: .7 1. In a tube socket, a base provided with apertures for'receivin'g the terminals of a tube, and'a plurality'of terminal clips for engaging said termmals supported on the under si e of said base, and each comprising a piece of fiat sheet metal bent with two side portions disposed in planes substantiall perpendicular to said base, parts of sai side portions disposed beneathone'of said terminal a ertures and being adapted to contact wit the tube terminal under tension,

and other parts projecting upwardly through said base and with their upper ends bent laterally to secure said clip to said base.

2. In a tube socket, a base provided with apertures for receiving the terminals of a tube, and a plurality of terminal clips'for engaging said terminals supported on the under side of said base, and each comprising a piece of fiat sheet metal bent with two side portions disposed in planes substantially perpendicular to said base, parts of said side portions at one end vof said clip disposed'beneath one of said terminal apertures, and being adapted to contact with 'the opposite sides of tube terminals under tension, and other parts projecting upwardly through said base and with their upper ends bent lat erally to secure said clip to said base.

3. In a tube socket, a base provided with apertures for receiving the terminals of a tube, and a pluralit of terminal clips for engaging said terminals supported on the under side of said base, and each comprising a piece of flat sheet metal bent with two side portions disposed in plaines substantially substantially in U-shape, with freely clip in place thereon.

perpendicular to said base, parts of said side portions at one end of saidclip disposed beneath one of said terminal apertures and being adapted to contact with the opposite sides of tube terminals under tension, other parts projecting upwardly through said base and with their upper end bent laterally to secure said clip to said base, and other projections extending upwardly into interlocking engagement with said base to hold said clip from twisting relative thereto.

4. terminal clip for tube sockets comprising a single piece of flat sheet metal bent rojecting end portions spaced laterally fi om each other, to hold a terminal under tension therebetween, and upwardly projecting securing portions adapted to be .extended through apertures in a base member with their upper ends bent'laterally to hold said 111. this 20 day of PAUL A. CHAMBERLAIN.
